LIGHT-EMITTING ELEMENT

Japanese Patent JP2014078699

A

To provide a light-emitting element having high luminescent efficiency.

A light-emitting element comprises between a pair of electrodes: a layer including a P-type host, a luminescent layer including a guest, a P-type host and an N-type host, and a layer including an N-type host. The P-type host and the N-type host are a combination to form an excited complex. According to analysis by a time-of-flight secondary ion mass spectrometer, among the layer including the P-type host, the luminescent layer and the layer including the N-type host, a layer having the highest secondary ion intensity of the N-type host is the luminescent layer, the layer having the next highest secondary ion intensity of the N-type host is the layer including the N-type host and the layer having the lowest secondary ion intensity of the N-type host is the layer including the P-type host.
